Replacing a light fixture

I am a new handyman and I need some help.... I want to change out a bathroom light fixture and need to know how to wire.

The wall outlet has three wires: white, tan, and a copper ground wire. The new fixture has white, black, and a ground wire. Questions are: 1) White to white and black to tan, correct? 2) What do I do with the two ground wires (one from wall, one from new fixture?

I know these are elementary questions but need help. Thanks a lot in advance.
